Claims.

This invention relates to a ring adapted for mounting in a sheet metalwall, for example, one wall of a container, and the mechanism for andprocess of making the ring. f

This application is a division of my application Serial No.43,698, filedOctober 5, 1935, now Letters Patent No. 2,151,702, dated March 28. 1939.

One object of the invention is to provide an improved process of makingrings capable of being readily and economically mounted in sheet metalwalls.

l Another object of the invention is to provide an improved process ofmanufacturing rings ready for mounting in a tight and rigid manner in ametallic wall.

-A further object of the invention is to provide an improved ringcapable of being rigidly mounted in a metallic wall against endwise androtative movement and so shaped that any formation of a neck orembossment of the wall as a part'- of the ring mounting is entirelyeliminated, thereby reducingthe cost of simplifying the manufacture ofcontainers, as well as permitting the ring to be mounted in cheap gradesof sheet metal.

Other objects of the invention will be apparent to those skilled in theart to which my invention relates from the following description takenin connection with the accompanying drawings,

In the drawings, referring particularly to Figs. 1 to 7, inclusive, Iindicates the shoe for a die mechanism, indicated as an entirety at 2.The shoe I is adapted to be secured to the bed of a suitable die press,which may be of any well known construction and is, therefore, notshown. The die mechanism 2 comprises a lower member 2a and an uppermember 2b, the latter having a shank 3 which is rigidly secured to thereciprocating member of the die press for movement therewith.

,The die member 2a consists of the following: 4 indicates a base seatedin a recess 5 formed in the shoe l and held therein against rotarymovement by a dowel pin 6. The base 4 is formed with a central circularrecess to receive the boss 1 formed integrally on the lower side of apolygonally shaped member 8 and concentrically thereto. The member 8 issupported by the boss in operative relation to that wall of an annularmember or ring 9 which is to be shaped by the die mechanism 2 ready formounting in a metal wall a of a container A (see Fig. 11a). Thefboss 1and member 8 are formed with an Fig. 11a is a fragmentary view of acontainer 55 axial opening (preferably a` through opening) I I) which isthreaded, and registers with an opening IUa formed in the shoe I, toreceive a bolt II, whereby these parts are rigidly secured together. Theboss 1 and member 8 are held'ina predetermined position on the based bya dowel pin I2.

The ring 9k is shown in Figs. 8 and 9 and'consists of a bodyvv portion9a having at one endan axially extending cylindrical wall 9b and alaterally extending flange 9c; and by preference the iiange may beprovided with one or more ears' 9d which are curved laterally t' serve'as' seal.-Y-`

ment) to engage and operate the die elements I9. The outer die part 24consists of the shank 3 (already referred to), an annulus 29 suitablysecured to the shank and a ring 30 suitably secured to the lower wall ofthe annulus 29, the inner wall of the ring being conical and serving asa cam 38' adapted simultaneously to engage the inclined complementarywalls on the outer ends of the die elements I9. The cam wall 30 is cutaway at diametrically opposite sides as shown at 30x in Figs. 2 and 3 toaccommodate the ears 9d. This wall may be providedI with a cut away 30a:opposite or in line with each die element |9 to receive the ears of thering 9 in any position in which it may be seated on the member 20.

From the foregoing description it will be seen that I first form thering as shown in Figs. 8 and 9, next the ring is positioned on the diemember 2a, as shown in Fig. 1, this view showing the upper die membermoved downwardly with the inner die part 23 (that is, the clampingmember 25) engaging the ring 9 and the outer die part ready to actuatethe die elements. Finally, by the further movement of the outer die part24, its cam ring simultaneously engages the die elements I9 and slidesthem inwardly radially (see Fig. 2), the effect of which is to shape thewall 9b into polygonal form or contour, as shown at 9b' in Figs. 10 and11, complementary to the shape of the member 8.

Next, I stamp in the metal wall an opening 3|, in which the ring is tobe mounted, such opening being similar in shape and size to the outerperiphery of the shaped wall 9b (see Fig. 11a). This wall a is hereshown as a head for a container A, but the ring may be mounted in theside wall or body 32 of the container. Next, a gasket I8 is ringed onthe wall 9b' within the gasket groove I and the wall 9b' inserted in theopening 3| as shown in Fig. 12. Finally, the wall a` and ring 9 arepositioned in a press of any desired construction carrying suitablyshaped die members, which are relatively moved to effect theirengagement with the ring and wall 9b', to swage the marginal portion ofthe latter over into engagement with the Wall a, as shown at 9b in Figs.13, 14, 17 and 18, thereby securely clamping the wall a around theopening 3| between the flange 9c and marginal portion of the wall 9b'.It will thus be seen that the ring is secured to the wall a againstmovement axially of the ring and by engagement of the flat faces orsides of the wall 9b' with the correspondingly shaped walls of theopening 3 I, the ring 9 is held against rotative movement. Such securingpermits a plug I4 or other device, when screwed into the ring 9, to beadequately tightened by means of the usual tool and removed from time totime without danger of affecting the fixed relation between the ring 9and wall a. This xed relation is such as to seal the joint between theseparts, but due to danger of rough or imperfect material and wear of thedies, the gasket IB is used to insure a sealing under all abnormalconditions.

Where the wall a is to be used as the head of a barrel or container, itsmarginal portion is connected to the body thereof as by double seaming,as shown at 33 in Figs. 12, 13 and 14. In such application of the ring,that portion of the Wall a surrounding the opening is preferably offsetoutwardly, into a plane parallel to the remaining portion of the head,equal to the thickness of the swaged-over portion Sha: so that thelatter will not project into the container beyond the head to therebyinsure the complete drainage of the container; also, the wall a may beprovided with an annular up-standing embossment a.' when desired.

The ears 9d permit a section of Wire 34 tov be threaded through them andone or more openings formed in portions of the plug I4 and their endssecured by a lead slug 35. As illustrative of such sealing means, theplug I4 is formed with a recess 36, preferably of polygonal shape, for asuitable tool and two side walls of thisrecess are formed with inclinedthrough-openings 31 through which the wire 34 passes.

When desired, the sealing may be effected by means of a cap`38 formed ofthin sheet metal and capable of ready distortion or mutilation to detecttampering and to prevent its re-application to the ring. The cap 38 issubstantially cup-shaped to t over the collar or wall 13', and permitits side wall or skirt to be circumferentially crimped into the grooveI3 around and below the shoulder I3. The skirt of the cap 38 may be longenough to accommodate the' flange I 4 on the plug I4, as shown in Figs.1'7, 18 and 19. Where the plug I4 is omitted, as shown in Fig. 19a, orthe flange on the plug is omitted so that when the plug is screwed intothe ring its outer end is substantially flush with the upper end of thering, the cap 38 may engage a gasket 39 positioned on the upper end ofthe ring to seal the opening. But if such plug is provided with a gasketthen the gasket 39 may be omitted if desired.

The cap 38 is preferably embossed with two relatively shallow continuousgrooves 48 extending from the lower edge of the skirt at one sideupwardly along the skirt across a portion of its top wall and down theadjacent portion of the skirt to its lower edge and also with a groove4| connected to or intersecting the grooves 4U. These grooves facilitatemutilation of the cap (see dotted lines 42 in Fig. 19) when it isdesired to remove it. The central portion of the top wall of the cap maybe embossed, as shown at 43, to dispose it above the marginal portion ofthe wall, which further facilitates the mutilation of the cap.
